Front light LED fabric light box cloth is used to make front light LED fabric light box, and its light transmittance is generally between 5-10%. This type of LED fabric light box cloth is more resistant to typhoons.
Therefore, it is mostly used to make large outdoor LED fabric light boxes, such as building billboards, highway roadside LED fabric light boxes, and city Optimus Prime LED fabric light boxes.
At present, large-scale outdoor LED fabric light boxes between 100 square meters and 400 square meters produced by China light box suppliers mostly use this kind of light cloth. The mesh cloth is designed and made according to the typhoon climate regions such as Taiwan and Fujian.
Since many meshes are densely arranged on the surface of such materials, the wind can pass through the surface of the light cloth, so the pressure of the typhoon on the LED cloth light box can be greatly reduced, so that the picture can be used outdoors for a longer time.
Because of this characteristic, mesh cloth is mostly used to make oversized signage advertisements and architectural advertisements. 95% of the large-scale color inkjet LED fabric light box pictures in the Chinese market use LED fabric light box fabric as the substrate.
